What is the area of a sector with radius 12 cm and central angle 150°?12 सेमी त्रिज्या और 150° केंद्रीय कोण वाले सेक्टर का क्षेत्रफल क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 60π cm²60π cm²
Convert the angle to radians: 150° = 5π/6. The sector area is A = ½r²θ = ½ × 12² × 5π/6 = 60π cm².कोण को रेडियन में बदलें: 150° = 5π/6। सेक्टर का क्षेत्रफल A = ½r²θ = ½ × 12² × 5π/6 = 60π सेमी² है।
